EXAMPLE 12.26

Interpreting software output. The output generated by SPSS for Bonferroni comparisons appears in Figure 12.15. The software uses an asterisk to indicate that the difference in a pair of means is statistically significant. Here, all 10 comparisons are reported. These results agree with the calculations that we performed in Examples 12.24 and 12.25. There are no significant differences except those already mentioned. Note that each comparison is given twice in the output.
